[OSM-talk] Uploading multiple tracks

thanks for the hint, will cope with it. The question is if it will 
create tracksegments in the resulting file; it was wrong to write them 
all into one tracksegment (my tracks do not end and start at the same 
point).

Is gpsbabel able to anonymize the timestamps as well? I know it can 
simply shift the timestamps, but I'd prefer to create some completely 
new ones. I tried Jörgs script, but it didn't work as expected and if I 
already use gpsbabel. it would be cool to do both steps with one tool.

Thanks & best regards,
